PURPOSE:To simplify the circuit constitution by connecting interface ports of multidrop electronic apparatus and lines with line converters having connectors between them and supplying power from one position of lines. CONSTITUTION:Interface ports 107-307 of a master electronic apparatus 105 and slave electronic apparatus 205 and 305 are connected to lines 109 and 209 with line converters 100-300 between them in the multidrop manner. Interface ports 107-307 and line converters 100-300 are connected by female connectors 106-306 and male connectors 102-302 having the same terminal arrangement. With respect to connection between line converters 100-300 and lines 109 and 209, pairs of female connectors 103a and 103b-303a and 303b are joined into one body respectively and are connected to line-side male connectors 98b, 108a, 108b, 208a, 208b, and 308a. Connectors 98b and 308a are terminated with resistances. A power source 185 is shared for power. Thus, a circuit where line conversion is easy and the operation is stable is formed easily.
